검증된 단계별 안내1
Recall the main stages of meiosis: Meiosis I and Meiosis II, each with Prophase, Metaphase, Anaphase, and Telophase phases.
Understand that during Anaphase I, homologous chromosomes separate, but sister chromatids remain together because centromeres do not split yet.
Recognize that during Anaphase II, the centromeres split, allowing sister chromatids to separate and migrate toward opposite poles.
Note that in Metaphase II, chromosomes align at the metaphase plate but centromeres have not yet split.
Conclude that the stage where centromeres split and chromatids move to opposite poles is Anaphase II.
